Abstract

PURPOSE: To prevent the molten slag from intermingling into the ladle from the converter, by blowing an inert gas into the molten steel from the surroundings of the tap hole of the converter and, at the same time, by closing the tap hole with the slide plate according to the measured value of the radiation energy from the outflow stream.
